It should also have been designed in every camera to have unique file names. It’s ridiculous they all don’t.
If ever you have a pixel die or get stuck, you can also manually set the date a couple months ahead and turn it off - it will most likely be fixed when it turns back on.
So THAT is that mysterious click-clack of the shutter that randomly appears on my A7S2. I've been putting off sending it in for repair, but now I can completely avoid that. Many thanks!
Do you happen to have a link to some documentation for it?
I personally used this trick twice to fix dead pixels on my camera, so I can attest to that.
For cameras without a mechanical shutter, there is instead an option to do it in the menu, for example : (https://helpguide.sony.net/ilc/2010/v1/en/contents/TP0003229...)
Maybe because the FX30 lacks the physical shutter, and instead relies on you putting a lens cao on? If so, I'd expect the A9iii to have the message too.
I think if you can see hot pixels when looking at the raw before demosaicing then the dark frame is not applied (which makes sense, since a DNG is supposed to be more or less a sensor snapshot).
If you do not see them after you processed the raw, I think that would just be your software filtering outliers as best it can, since it would have no way of knowing about the dark frame. I doubt it embeds the dark frame in every DNG, would take up extra space and I am not sure the format even supports that, so likely it just keeps the latest dark frame in memory and applies as part of internal pipeline.
On a Sony E-mount camera, the ultrasonic sensor cleaning doesn't do pixel remapping, only the date trick (or the menu option on electronic shutter models) works to trigger it manually.
Also, a dead pixel is not a ruined photo, it’s a minor inconvenience in editing at worst. And every photo I take on a FF is getting edited, the gorgeous RAW output is what I’m there for.
Do you have software that automatically fixes this issue in all the pictures at once? Because as a non-professional I can only think of a very manual approach.
On my old phone, dust made its way into one of the cameras and now all of those photos are forever ruined (or until I find a way to somewhat automate this fixing)

In the case of a reference photo it is closing, not opening, taking a read of the sensor, then opening again.
The shutter, which is replaceable, is normally rated, for 200k-1mm actuations MTBF.
Even taking a reference photo every day won’t truly impact shutter life.
Anecdotally: I have a 20 year old Canon 1D that is 50% over it’s rated shutter life, and that camera was used for photojournalism (used HARD) for most of its life.
It sucks, but it is what it is, and it's not too difficult to batch remove dead pixels - if you even notice them.
